Opis:
Human or animal hair is considered to be a good indicator of the content of bioelements or toxic elements in human and animal organism. Its analysis is a good alternative for the arduous obtaining blood or biopsy samples. The aim of the performed research was the assessment of some chosen bioelements in the organism of European bison on the basis of their analysis in hair. The investigation material comprised hair samples obtained from 22 animals. All animals were divided into groups according to gender (males, females) and age (calves up to one year of age and animals older than 2 years). Samples were mineralized in nitric acid, under pressure in the microwave apparatus. The content of phosphorus, sulphur, magnesium, iron, titanium and vanadium were determined in hair samples. The content of these elements was determined using the ICP-AES method in accredited laboratory. The accuracy of determinations was tested using the standard reference material. The mean content of phosphorus in hair amounted to 245.14 mg · kg–1, SD 65.00, magnesium 97.32 mg · kg–1, SD 33.16, iron 119.48 mg · kg–1, SD 83.31 and titanium 2.368 mg · kg–1, SD 2.097. In case of these elements, differences depending on gender and age were statistically insignificant. Mean content of sulphur in the European bison hair amounted to 3.41% with equalized content in the herd (SD 0.22%). Here also statistically insignificant differences depending on gender were observed. However, a statistically significant difference (p ≤ 0,05) was demonstrated which depended on animal age. Mature European bisons had more sulphur in hair as compared to calves. The concentration of vanadium (0.362 mg · kg–1, SD 0.396 on the average) significantly differed in hair depending on the European bison age with much higher values in adult animals (calves 0.260 mg · kg–1, animals older than 2 years 0.686 mg · kg–1). Similar data were obtained while investigating hair of sea mammals.

Opis:
Iron (Fe) represents a highly essential element for various biological processes. In spite of this very little is known as regards its status in mammalian reproductive tissues and factors that may potentially influence it. At the same time, there is an ongoing debate as to whether analyses of the Fe content in hair can provide reliable information on its tissue burden. Therefore, the aim of the present study was to investigate the content of Fe in the testicular and uterine tissues, and hair of the domestic cat (Felis catus) and how this content relates to an animal’s age, weight, physical activity, inhabited environment and diet. The median Fe content in the feline reproductive tissues amounted to 50.8 ppm and in hair to 180.2 ppm. As found, free-ranging cats were characterized by a significantly higher Fe content in reproductive tissues, particularly in the uterus. Age, weight and physical activity had no effect on determined Fe levels. The type of commercial diet (wet, dry or combined) given to household cats also had no influence upon Fe status in hair and tissue although males fed exclusively on dry food had a lower Fetestis:Fehair ratio. Hair Fe level was positively correlated with that found in the reproductive tissues (Rs=0.30). This study extends the body of information on Fe distribution in felines, demonstrates the difference between free-ranging and household cats and provides evidence that Fe hair status may, at least partially, reflect the status of this element in the feline reproductive system.

Opis:
This study was designed to assess alterations of hormone and cytokine levels associated with growth period during puberty in Honamli goats which were identified as a new goat breed and had one of the highest meat production potential among the other goat breeds in Turkey. Honamli goats are originated from native hair goats, so parallel studies of sampling and analyzing were conducted also in native hair goats which have moderate meat production. Blood serum samples of Honamli (n=90) and native hair goats (n=90) were obtained from the pure herds in Korkuteli and Ka districts of Anatolia. Concentrations of growth hormone (GH), myostatin (MSTN), insulin-like growth factor (IGF), growth hormone releasing hormone (GHRH), growth hormone releasing peptide (GHRP), leptin, transforming growth factor-betal (TGF-ß1) and vascular endothelial cell growth factor (VEGF) levels were measured by ELISA in each breed in the age groups of 4, 8 and 12 months. The present results indicate interesting correlations among the age groups and all the examined hormone and cytokine parameters exhibited significant (P<0.05 and P<0.001) differences. The parameters investigated were usually begun to increase after 4 months of age in the both breeds and sexes. Therefore, this paper supported the view that the beginning of hormonal alterations of goats could occur at 4th month of age. The results reported here emphasize the primary role played by GH, MSTN, IGF-1, leptin, GHRH, GHRP, TGF-ßi and VEGF in the first year growth period of goats.

Opis:
Secondary plant substances - glucosinolates and saponins reduced seed germination and seedling growth of lettuce. Saponins showed greater inhibitory effect on both germination and growth of lettuce seedlings than glucosinolates. The effect depended on the concentration of these compounds in the ground. Tested compounds caused abbreviation of roots, browning their tips and prevented root hair development.
Testowano wpływ roślinnych metabolitów wtórnych: saponin lucerny i glukozynolanów rzepaku na kiełkowanie nasion sałaty. Stwierdzono hamujący wpływ obu badanych związków na kiełkowanie. Znacznie silniejsze działanie wykazywały saponiny, przy czym efekt ten zależny był od ich stężenia w podłożu. Badane związki wpływały nie tylko na liczbę skiełkowanych nasion, ale również na wygląd siewek (skrócenie korzonków, brunatnienie ich końców, brak włośników).
